adware removal

hey guys, how do i go about removing adware from my pc. Norton picks these files up and I tried deleting them but have no success. They seem to just come right back. Any suggestions as to how I can rid of this??? Thanks!

settings/control panel

add remove programs

At risk of stating the obvious,....

Adaware 6.0 and Spybot. Both are free downloads.
